The curved surface 142a may extend in a radial direction of the plate part 141 as it moves away from the fan 110 in the front-rear direction. That is, the airflow guide 142 may include a curved surface 142a that moves away from the rotation axis R of the fan 110 as it moves away from the fan 110 in the front-rear direction.

Since the airflow guide 142 is formed to have a ring shape and has an outer surface that is a curved surface 142a, the air that has passed through the guide vane 131 flows smoothly along the outer surface 142a when it collides with the airflow guide to the outlet (11) can be guided to the side. Accordingly, it is possible to prevent or reduce the formation of a vortex by the air that has passed through the guide vane 131 .

The plate part 141 may block part or all of the opening 133a of the accommodation space 133 to prevent the airflow passing through the guide vane 131 from entering the accommodation space 133 of the body 132 . The plate part 141 of the cover panel 140 may include a heat dissipation hole 141a communicating with the heat dissipation passage part 133c.

In order to effectively shield the accommodation space 133 of the body 132 , the plate part 141 may cover 75% or more of the area of the opening 133a of the accommodation space 133 .

As such, the plate portion 141 prevents the airflow passing through the guide vane 131 from flowing into the accommodation space 133 , and the airflow guide 142 effectively removes most of the air that has passed through the guide vane 131 . Since it is possible to guide to the outlet 11 and minimize the generation of vortex, the amount of air discharged from the outlet 11 of the air purifier 1 can be increased, and flow loss and flow noise due to the vortex can be minimized.

Although the technical idea of the present invention has been described above by way of specific embodiments, the scope of the present invention is not limited to these embodiments.
